"deinit" usb_cdc_4g_module (AEGHB-300)

[aiotfactory]

Hello,

How to deinit usb_cdc_4g_module? I tried esp_modem_default_destroy(dce->dte), but it will reports as below:

I (21711) esp-netif_lwip-ppp: Connected I (21711) esp-netif_lwip-ppp: Name Server1: 211.136.17.107 I (21711) esp-netif_lwip-ppp: Name Server2: 211.136.20.203 I (21716) usb4gutil: IP event! 6 I (21720) usb4gutil: Modem Connected to PPP Server I (21726) usb4gutil: ppp ip: 10.203.162.141, mask: 255.255.255.255, gw: 10.64.64.64 I (21734) usb4gutil: Main DNS: 211.136.17.107 I (21739) usb4gutil: Backup DNS: 211.136.20.203 W (21745) usb4gutil: PPP netif event = 266 E (26749) esp-modem: esp_modem_default_destroy(100): Cannot destroy dce or netif_adapter I (26752) util: Free heap all: 2202239 I (26752) util: Free heap internal: 116871 W (26752) USB_HCDC: line 267 HCD_PORT_EVENT_DISCONNECTION I (26762) USB_HCDC: hcd port state = 7 W (26766) USB_HCDC: Resetting USB Driver W (26771) USB_HCDC: Waitting for CDC task delete I (26776) USB_HCDC: pipe state = 0 I (26780) USB_HCDC: pipe state = 0 I (26984) USB_HCDC: CDC task deleted W (26986) USB_HCDC: Resetting default pipe I (26986) USB_HCDC: pipe state = 0 I (27186) USB_HCDC: hcd recovering I (27236) USB_HCDC: Waitting USB Connection I (27236) USB_HCDC: Port power: ON W (27784) usb4gutil: usb4g_init W (27787) USB_HCDC: USB Driver has inited E (27787) esp-modem-dte: esp_modem_dte_new(382): usb driver install failed

@achao1104 This operation is not supported yet, our next plan is to improve the stability of the application, and finally we will consider dynamic loading and unloading
